strain gauge sensor

[susheel]

can you please help me interface a s-shaped strain gauge with a 8051 microcontroller that indicates the maximum load and tare load

Hi Susheel,

you should use ADC to interface strain gauge to 8051. Follow below interface

Strain Gauge –> Instrumental Amplifier –> ADC –> 8051

Post your further doubts.

All the best.

many thanks!

i used AD7799 to directly connect to the load cell as its got an on-chip amplifier …

 

but i cannot figure out how to connect it to 8051.please help
thanks again

Good Susheel, use pins DOUT/RDY, DIN, SCLK, CS of AD7799 to interface with 8051.

DOUT/RDY pin ofAD7799 to Rx pin of 8051

DIN pin of AD7799 to Tx pin of 8051

SCLK pin of AD7799 to CLK pin of 8051

CS pin of AD7799 to I/O pin of 8051.

Also refer AD7799 data sheet to write code & further information to communicate.

thanks a lot!
you’ve broken it down for me. sure thing!
